3 Terms and definitions
For the purpose of this document, the terms and definitions defined in GB/T 15706-2012 and GB/T 36484 as well as the following apply.
3.1
hazard
potential source of harm
[Source: GB/T 15706-2012, 3.6]
3.2
risk
combination of the probability of occurrence of harm and the severity of that harm
[Source: GB/T 15706-2012, 3.12]
3.3
risk assessment
the entire process including risk analysis and risk evaluation
[Source: GB/T 15706-2012, 3.17]
3.4
emergency stop
emergency stop function
a function intended to:
——prevent ongoing or reduce existing dangers to personnel, damage to the machine or work in progress;
——be triggered by a single person's action
[Source: GB/T 15706-2012, 3.40]
3.5
interlocking device
mechanical, electrical or other type of device used to prevent a hazardous machine function from operating under specific conditions (usually when the guard is not closed)
[Source: GB/T 15706-2012, 3.28]
3.6
safety function
machine function whose failure immediately results in an increase in risk
[Source: GB/T 15706-2012, 3.30]
3.7
hazard zone of working
area on the metalforming machinery where workpiece processing is completed
Note: Such as the space included in the projection of the tools (including auxiliary devices) installed on the relatively moving working parts or the reciprocating linear moving working parts onto the worktable in the stroke direction; or the space included between the flame, laser, high-pressure fluid and the workpiece.
3.8
working stroke
stroke of the reciprocating working part of the metalforming machinery from the fully open position to the fully closed position
3.9
safety distance
minimum distance between the protective device and the hazard zone of working to ensure safety
3.10
multi-synchronous actuation
operation mode in which when two or more operators perform operations together, each person operates the two-hand control device simultaneously to start the working part
3.11
impeding device
physical obstacle (such as a low barrier, railing, etc.)
Note: The setting of physical obstacles shall not prevent personnel from entering the hazard zone, but can block free access and reduce the probability of entering the hazard zone by setting obstacles.
[Source: GB/T 15706-2012, 3.29, modified]
3.12
remote service
remote control of metalforming machinery for data exchange to achieve fault finding, diagnosis, maintenance, data analysis or optimized remote control purposes
4 Hazard identification of metalforming machinery
4.1 Risk assessment of metalforming machinery shall be carried out in accordance with the relevant provisions of Chapter 4 and Chapter 5 of GB/T 15706-2012.
4.2 When identifying hazards, the hazards that may arise under various conditions during the service life of the metalforming machinery (commissioning, operation, adjustment, cleaning, repair and maintenance) shall include at least:
——Unexpected start-up;
——Failure of the control system;
——Hazards arising from operators and other personnel entering the hazard zone;
——Intended use and reasonably foreseeable misuse;
——Other significant hazards related to metalforming machinery.
